자바스크립트 중단

i가 3일 때 루프에서 벗어나십시오.

let text = "";
for (let i = 0; i < 5; i++) {
  if (i === 3) break;
  text += i + "<br>";
}
let text = "";i = 0;
while (i < 5) {
  text += i + "<br>";
  i++;
  if (i === 3) break;
}

아래에 더 많은 예가 있습니다.


정의 및 사용

break명령문이 스위치 또는 루프에서 벗어납니다 .

스위치에서는 스위치 블록에서 나옵니다. 이렇게 하면 스위치 내에서 더 많은 코드 실행이 중지됩니다.

루프에서 루프를 벗어나 루프(있는 경우) 이후에 코드를 계속 실행합니다.


레이블 사용

명령문 은 break레이블 참조를 사용하여 JavaScript 코드 블록에서 벗어날 수 있습니다(아래 "추가 예제" 참조).

레이블이 없으면 break는 루프나 스위치 내부에서만 사용할 수 있습니다.


통사론

break;

선택적 레이블 참조 사용:

break labelname;


더 많은 예

케이스가 true일 때 스위치 블록에서 벗어나십시오.

let day;
switch (new Date().getDay()) {
  case 0:
    day = "Sunday";
    break;
  case 1:
    day = "Monday";
    break;
  case 2:
    day = "Tuesday";
    break;
  case 3:
    day = "Wednesday";
    break;
  case 4:
    day = "Thursday";
    break;
  case 5:
    day = "Friday";
    break;
  case 6:
    day = "Saturday";
    break;
}

목록에서 벗어나기:

let text = "";
const cars = ["BMW", "Volvo", "Saab", "Ford"];

list: {
  text += cars[0] + "<br>";
  text += cars[1] + "<br>";
  text += cars[2] + "<br>";
  break list;
  text += cars[3] + "<br>";
}

예시

중첩 루프에서 벗어나기:

// The first for loop is labeled "Loop1"
Loop1:
for (let i = 0; i < 3; i++) {

// The second for loop is labeled "Loop2"
Loop2:
  for (let i = 10; i < 15; i++) {
    if (i === 12) break Loop1;
  }
}
